- the cage 22 comprises two cage halves 24, 26.
- Each cage half 24, 26 includes a radially extending segment 25, 27 respectively with circumferentially spaced openings 30, 32 respectively.
- Each radially extending segment 25, 27 includes portions 47, 48 circumferentially between the plurality of openings 30, 32.
- the openings 30, 32 are preferably generally rectangular and configured to receive the rolling elements 2.
- the cage halves 24, 26 are interconnected with the openings 30, 32 radially and circumferentially aligned and with at least portions such as portions 47, 48 of the radially extending segments 25, 27 abutting one another along a plane P.
- the centerline of each of the rolling elements 2 lies in or in proximity to the plane P.
- circumferential flanges 28 are provided at the inner and outer diameters of the radial portions 25, 27 to provide a piloting surface for the thrust bearing assembly 20 and to provide additional structural rigidity for the cage 22.
- Each opening 30, 32 has a flange 34 about at least a portion of or the entire opening perimeter.
- Each flange 34 extends outwardly from the plane P.
- the flanges 34 are formed in such a way as to guide and retain the rolling elements 2.
- Fig. 2 illustrates how the configuration of the thrust bearing assembly 20 allows an effective lubricant film to be developed.
- lubricant can be captured in the generally triangular area defined between the rolling element 2 and the two abutting cage halves 24, 26.
- the abutting portions 47 and 48 close off the triangular area between the flanges 34 and prevent the lubricant from escaping circumferentially from adjacent the rolling element 2.
- Lubricant that either splashes into or is carried by adhesion to the rolling element 2 into this generally triangular area will tend to accumulate in this area and help promote a hydrodynamic lubricant film between the rolling element 2 and the surfaces 35 of the flanges 34.
- the smooth, generally convex surfaces 35 of the flanges 34 will minimize the "scraping" of lubricant off the rolling element 2 and will help maintain the presence of lubricant in the generally triangular area adjacent the rolling element 2.
- the smooth surfaces 35 also minimize direct contact between the rolling elements 2 and the cage 22, thereby reducing friction and wear.
- FIG. 3 A form of the flange construction for rolling element openings 30, 32 according to the invention is shown in Fig. 3 .
- the cage halves 24A, 26A still abut on the plane P extending along or approximately along the centerline of the rolling elements 2, however, the flanges 34A along the length of the rolling elements 2 are divided into separate tabs 37.
- These tabs 37 are formed to present a smooth, generally conforming surface to the rolling elements, which is a variation of the smooth, generally convex surfaces 35 shown in Fig. 2 .
- the tabs 37 are directed towards the opposite side of the rolling elements 2 rather than the closest side.
- the tabs 37 are arranged so as to alternate on a portion of the perimeter such as along the length of the rolling elements 2.
- This sturdier construction allows a greater length of flange 34A. This additional length allows for greater flexibility in the shape of the flange 34A and is particularly useful for bearing assembly 20 with rolling elements having smaller diameters and that have tighter space restrictions for the cage 22.
- FIG. 20 shows a portion of a prior art cage 3A, taken near the inner diameter. It can be seen that the corners 13 of the cage openings 5 must be at right angles and relatively sharp to clear the rolling elements. The trapezoidal shape of the cage bars 14 between the openings 5 exacerbates this situation in the prior art designs because there is minimal cage material to resist stresses caused by radial and torsional loads on the cage. Referring to Fig.
- the flanges 34 of the thrust bearing assembly 20 includes a continuous surface at the corners 31 of the generally rectangular openings 30, 32.
- This structure can increase the cage strength in two ways.
- the flanges 34 provide additional material all around the openings 30 for the rolling elements 2. In the areas of high stress, such as corners 31 near the inner diameter, the flanges 34 can as much as double the amount of material available to resist these stresses.
- the cage openings 30 are further strengthened by the actual shape of the flanges 34.
- the flanges 34 are designed in such a way that the stresses are directed away from the corners 31 of the openings 30.
- the combination of additional material and optimized stress flow results in cage strength that is several times greater than that of the prior art constructions.

Abstract
Description

- Referring to
Figs. 11 and 12 , an example of a prior art needle roller thrust bearing 1 is shown. Thebearing 1 includes a plurality of cylindricalrolling elements 2 arranged radially from a center of rotation. Therolling elements 2 are retained and guided by abearing cage 3, which forms the primary structure of thebearing 1. - There are several types of construction currently used to produce metallic needle roller bearing
cages 3.Figs. 13 and 14 show a thrust bearing 1A with acage 3A that is constructed of two halves 4. Each half 4 hasrectangular window openings 5 which are slightly smaller in width than the diameter of therolling elements 2.

Certain terminology, for example, "top", "bottom", "right", "left", "front", "frontward", "forward", "back", "rear" and "rearward", is used in the following description for relative descriptive clarity only and is not intended to be limiting.
- Referring to
Figs. 1 and2 , a needle rollerthrust bearing assembly 20 is shown. Thethrust bearing assembly 20 includes acage 22 supporting a plurality of preferably cylindricalrolling elements 2 arranged radially from a center of rotation (not shown). Thecage 22 comprises twocage halves cage half segment openings segment portions openings - The
openings rolling elements 2. Thecage halves openings portions segments rolling elements 2 lies in or in proximity to the plane P. In this example,circumferential flanges 28 are provided at the inner and outer diameters of theradial portions thrust bearing assembly 20 and to provide additional structural rigidity for thecage 22. - Each opening 30, 32 has a
flange 34 about at least a portion of or the entire opening perimeter. Eachflange 34 extends outwardly from the plane P. Theflanges 34 are formed in such a way as to guide and retain therolling elements 2. An advantage of this design over theprior art cage 3 constructions is that any portion of thecage 22 of the present example that contacts therolling elements 2 has a smooth rolled and formed surface. In contradistinction, as shown inFig. 19 , the surfaces that contact therolling elements 2 of thecage 3A are pierced such that theopening 5 is defined by rough piercedsurfaces 10 which can interfere with proper lubrication and also lead to wear. -
Fig. 2 illustrates how the configuration of thethrust bearing assembly 20 allows an effective lubricant film to be developed. Specifically, lubricant can be captured in the generally triangular area defined between therolling element 2 and the twoabutting cage halves abutting portions flanges 34 and prevent the lubricant from escaping circumferentially from adjacent therolling element 2. Lubricant that either splashes into or is carried by adhesion to the rollingelement 2 into this generally triangular area will tend to accumulate in this area and help promote a hydrodynamic lubricant film between the rollingelement 2 and thesurfaces 35 of theflanges 34. The smooth, generallyconvex surfaces 35 of theflanges 34 will minimize the "scraping" of lubricant off the rollingelement 2 and will help maintain the presence of lubricant in the generally triangular area adjacent the rollingelement 2. The smooth surfaces 35 also minimize direct contact between therolling elements 2 and thecage 22, thereby reducing friction and wear. - A form of the flange construction for rolling
element openings Fig. 3 . In this case, the cage halves 24A, 26A still abut on the plane P extending along or approximately along the centerline of the rollingelements 2, however, theflanges 34A along the length of the rollingelements 2 are divided intoseparate tabs 37. Thesetabs 37 are formed to present a smooth, generally conforming surface to the rolling elements, which is a variation of the smooth, generallyconvex surfaces 35 shown inFig. 2 . However, thetabs 37 are directed towards the opposite side of the rollingelements 2 rather than the closest side. In order to secure retention of the rolling elements in both directions, thetabs 37 are arranged so as to alternate on a portion of the perimeter such as along the length of the rollingelements 2. This sturdier construction allows a greater length offlange 34A. This additional length allows for greater flexibility in the shape of theflange 34A and is particularly useful for bearingassembly 20 with rolling elements having smaller diameters and that have tighter space restrictions for thecage 22. - In addition to improved wear and lubrication, another advantage of the
cage 22 ofthrust bearing assembly 20 is the substantially greater strength it provides compared to existing types of cage construction. This is particularly important in those areas with high concentrations of stress, such as the corners of the cage openings.Figure 20 shows a portion of aprior art cage 3A, taken near the inner diameter. It can be seen that thecorners 13 of thecage openings 5 must be at right angles and relatively sharp to clear the rolling elements. The trapezoidal shape of the cage bars 14 between theopenings 5 exacerbates this situation in the prior art designs because there is minimal cage material to resist stresses caused by radial and torsional loads on the cage. Referring toFig. 4 , theflanges 34 of thethrust bearing assembly 20 includes a continuous surface at thecorners 31 of the generallyrectangular openings flanges 34 provide additional material all around theopenings 30 for therolling elements 2. In the areas of high stress, such ascorners 31 near the inner diameter, theflanges 34 can as much as double the amount of material available to resist these stresses. Thecage openings 30 are further strengthened by the actual shape of theflanges 34. Theflanges 34 are designed in such a way that the stresses are directed away from thecorners 31 of theopenings 30. The combination of additional material and optimized stress flow results in cage strength that is several times greater than that of the prior art constructions. - There are several possible ways to interconnect the two
cage halves rigid cage 22. Using the embodiment of the sealedbearing assembly 20 as shown inFigure 3 , the rollingelements 3 can be snapped past thetabs 37 to join the cage halves 24A, 26A and form a unitarythrust bearing assembly 20. - Several additional examples of interconnecting the cage halves 24, 26 are shown in
Figs. 5-8 , however, other methods may also be utilized. Referring toFig. 5 , the cage halves 24, 26 are spot welded 40 at various points along the abuttingradial portions Fig. 6 illustrates a mechanical joint 42 created by partially piercing theradial portions halves Fig. 7 , acircumferential band 44 is secured to the inner and/or outer diameters of the cage halves 24, 26 about the inner orouter flanges 28 to secure thehalves Fig. 8 , one of the cage halves 26B does not have a flange, but instead terminates in theradial portion 27. Theother cage half 24B has aflange 46 extending from theradial portion 25 that extends toward and wraps around theradial portion 27. While theflange 46 is illustrated as being along the cage outer diameter, it is also possible to provide theflange 46 along the cage inner diameter. - Another advantage is that various combinations of differently sized
circumferential flanges 28 at the inner and outer diameter of thecage 22 can be used to control lubricant flow within the bearingassembly 20. In some cases it is desirable to restrict or partially restrict the lubrication flow, while in other cases it is desirable to allow as much flow as possible. For example,Fig. 9 shows thethrust bearing assembly 20 ofFig. 1 positioned between twostructures circumferential flanges 28 restrict the radial oil flow past the bearingassembly 20.Fig. 10 shows anotherthrust bearing assembly 20C positioned betweenstructures thrust bearing assembly 20C includes acage 22C withinterconnected halves halves assembly 20C. Other designs could incorporate partial orshorter flanges 28 to partially restrict flow. - The present invention addresses the essential requirements of a thrust bearing cage, namely, structure, guidance and retention, in a manner than greatly improves both the strength, rigidity, lubrication advantages, and the efficiency of the bearing assembly. Further, a low profile of the bearing assembly can be achieved.
- The invention is defined by the following claims.
